#EHD068 Distance Meter.

Distance Meter.

[ Distance Meter ]

This is a very simple and workable project. To measure the distance of an object, we can measure it with this distance meter. An interesting and workable project that you can create very easily by following the rules given by us.

Block Diagram:

        Circuit Diagram:

     Advantages:

       -  The distance can be easily measured.

         -  Small in size so easy to carry.

               -    Rechargeable System. 

           Applications:

          It can be used very well to measure the length of an object. 

     Required Instrument:

    - Arduino Nano.

    - Ultrasonic Sensor.

    - OLED Display.

    - Battery.

    - Charger Socket.

    - Switch.

     Summary:

This project is truly interesting and workable. By following the rules given to us, it will work for 100%. You can make it for your own use as it has very high accuracy.

N.B: If you have any problems working, please contact us and we will assist you.in-shaa-allah.
